GROOVlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 565,213, dated August 4, 1896.

Application filed June 6, 1894:. Serial No. 513,653. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY W. MORGAN, of Rochester, in the county of Monroe, in the State of New York, have invented new and useful Improvements in Grooving-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in grooving-machines of the particular class described in my Patent No. 517,705, of April 3, 1894, and has for its object the production of a simple, practical, and highly effective device for forming dovetailed grooves in the ends of boards or shooks designed to be dovetailed together; and to this end it consists, essentially, in a frame, a support for the lower edges of the boards, shooks, or other articles to be grooved supported on the frame, a rotary cutter-head supported by the frame and having its cutting-face arranged at an angle less than a right angle with the face of said support adjacent to the boards or articles to be grooved, and means for feeding the ends of the boards, shooks, or other articles across the face of the cutter-head.

The invention also consists in the general construction and arrangement of the component parts of my grooving-machine, all as hereinafter more particularly described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in allthe views.

Figures 1. and 2 are respectively top plan and side elevation of my improved groovingmachine, having a portion of its frame broken away. Fig. 3 is an enlarged longitudinal vertical sectional view taken on line 3 3, Fig. 1, a box-shook of narrow width being interposed between the cutter-heads. Fig. 4 is an iso metric view of four box-shooks similar to those formed by my machine shown as clovetailed together in position for forming a box. Fig. 5 is a longitudinal vertical sectional view similar to Fig. 3, the cutter-heads being shown as separated a greater distance than at Fig. Figs. 6 and 7 are detail elevations of opposite sides of a portion of a side boxshook and adjacent portions of the knives or saws of the cutter-heads for forming a clove tail groove therein. Fig. 8 is a detail sectional view taken on line 8 S, Fig. 1, the cutter-heads being shown as of the same diameter and as operatively engaged with end shocks of substantially the same size as the ones illustrated at Fig. 4:; Fig. 9 is a transverse vertical sectional view taken on line 9 9, Fig. 8. Figs. 10 and 11 are detail elevations of a portion of an end shock and the adjacent portion of the knife or saw of a cutter-head for forming the desired dovetail groove therein. Fig. 12 is a top plan view of a detached clamping-jaw suitable for use with my grooving-machine; and Fig. 13 is a detail vertical sectional view taken on line 13 13, Fig. 1.

The frame A, only a portion of which is here illustrated, is of any desirable form, size, and construction, and is provided with crosswise and lengthwise guides a a, which are of any suitable construction. A carriage B for feeding the boards, shocks, or other articles to be grooved is movable lengthwise of the guide a, and may be actuated by any suitable feeding mechanisrmhere illustrated as a driving-shaft or spindle O, journaled in bearings A A.

A pinion O is mounted upon the shaft or spindle G and engages a rack Z) at the lower face of the carriage B. The spindle C may be revolved by a hand-wheel C or suitable power-transmitting mechanism, not necessary to herein illustrate or describe, and, when revolved, reciprocates the carriage B to and fro in the guide a.

A bearing 6 and a block E", supporting a second bearin g e, are movable lengthwise of the uide a and are provided with substantially parallel rotary shafts e 6 carrying oppositely-arranged cutter-heads E E, consisting of a series of saws or knives arranged one above the other. Any suitable feeding mechanism may be used for reciprocating the bearing e and the block E" in the guide cl, but I have here illustrated a screw F, journaled in bearings A A as connected to said bearing and block for this purpose. The screw F is provided with a hand-wheel F, and its extremities are screw-threaded in opposite directions and are passed through screw-- clearly illustrated, the pulley c is of consid-- erable width for permitting lengthwise movement of the bearing e without disengagement of the'corresponding belt from said pulley.

The block E is provided at its upper face with a suitable upwardly-inclining guide E extending from its inner edge, and the bearing 6 is movable lengthwise of the guide E and is thereby raised and lowered. To effect this movement of the bearing 6, the shaft, F is revolved, and the block E is held stationary by suitable fastening means, as apin E registering with perforations E d formed, respectively;in the block E and the frame A. The upward movement of the bearing e is essential for maintaining the required angle of the opposite sides of the grooves formed by the cutter-heads, and is permitted by the sliding lug c*. I

If desired, the bearing 6 may be fixed to the block E by suitable. fastening means, as

a pin E passed through perforations E E in the bearing e and the block E, and consequently if the pin E is withdrawn from its operative position and the screw F is revolved the block E, carrying with it the bearing e, is moved lengthwise of the guide a.

When the sides, boards, or shooks g of the box G are being grooved, the pin E is withdrawn from its operative position and the screw F is revolved for separating the bearings e c the desired distance to permit the passage of the box-shooks 9 between the cutterheads E E and when the end boards or shooks g are being grooved the pin E is withdrawn from its operative position and the screw F revolved for sufficiently separating the bearing 6 and the block E. E for grooving the side boards or shooks g are formed conical and are arranged with the large end of each opposite the small end of the other, and those for grooving the end boards or shooks g are formed of substantially the same diameter and are arranged substantially parallel.

The lower edges of the box-shooks are mounted upon suitable supports H H of any desirable form, size, and construction. As here illustrated, these supports are fixed to the bearings e e by nuts h, and are provided with movable attaching rails or bars h h, having their opposite ends secured to the supports H H by fastening means, as bolts 7L2 72.2.

The cutter-heads E As the bearing e is elevated the corresponding support H, secured thereto, is similarly elevated, and box-shooks mounted upon the 7 supports H H are arranged at the desired angle for permitting the conical cutter-heads E E to form the required grooves g in their opposite edges.

As clearly seen at Fig. 5, the lower edges the box-shooks, as will also be seen upon rcference to Fig. 5, is but substantially half as great as the inclination of the guide E of the block E. This difierence in inclination is necessary, owing to the fact that bothcutterheads are simultaneously adjusted and only one moved in an inclined plane.

As the carriage B operates to feed the boxshooks g, arranged at the desired inclination between the conical cutter-heads E E, the separate saws or knives of the cutter-heads operate to out corresponding portions of the dovetail grooves g in the adjacent ends of the box-shooks g, as seen at Fig. 6. The carriage is then retracted, and the box-shooks are re versed end for endand the carriage then op erated to again feed the box-shooks g between the cutter-heads for forming theremaining portions of the grooves g therein.

The carriage B is provided with suitable jaws I I for clamping the box-shooks and holding the same in their designed position when passed between the cutter-heads. These jaws are each provided at opposite edges with engaging pieces it, which may be moved vertically, and are provided with. grooves or guides L. for receiving ribs or shoulders 2' upon the main portions of the corresponding jaws I.

It is evident that the angles of the grooves cut by my improved grooving-machine when conical cutting-heads are used and the boxplane and the fastening-pin E is withdrawn 1 from operative position. The bearing 6 is then secured by the fastening-pin to the block E, and the cutter-head E and block E are moved lengthwise of the frame A for effecting the desired separation of the cutterheads EE. The boards or shooks g, inclined either backwardly or forwardly, as shown at Figs. 9, 10, and 11, from their loweredges upwardly, are interposed between the jaws I I, and their lower edges are mounted upon the supports H H, and when passed across the cutting-faces of the uniform cutter-heads dovetail grooves g are formed, as clearly seen at Figs. 11 and 12.

The jaws I are provided with removable engaging pieces 4 having their adjacent faces arranged substantially parallel and suitably inclined for holding the box-shocks g at the desired inclination. The engaging pieces 11 are provided with ribs i movable in guides in the engaging pieces 1' t and are held in operative position by suitable fastening means 1;. When the end boards, inclined either forwardly or rearwardly, have been passed across the cutting-faces of the cutter-heads E E, the removable engaging pieces 12 i are withdrawn and are oppositely arranged, so that their adjacent faces incline in the reverse direction, and the end boards similarly arranged, as shown at Fig. 11, are clamped between the jaws I I and again passed across the cutting-faces of the cuttingheads.

It will be particularly understood that I do not herein claim any of the features of construction of the grooving-machine set forth in my aforesaid patent, and that I have illustrated and briefly described the means for adjusting the cutter-heads and the carriage, clamping-jaws, and supports for the boards or shocks when being grooved merely for the purpose of elucidating my present invention. It will also be understood that my present invention is not limited to any particular construction of the aforesaid parts.

The operation of my invention will be readily understood upon reference to the foregoing description and the accompanying drawings, and it is evident that it is simple, practical, and highly effective, and provides box-shocks with grooves suitable for dovetailing the shooks together, and thereby forming a box of great strength and desirability. It is evident, however, that considerable change may be made in the general construction and arrangement of the parts of my grooving-niachine without departing from the spirit of my invention, and consequently I do not herein specifically limit myself to such exact construction and arrangement.
